Application filedFebruary 28, 1923. 'SerialNo. 621,378.

l7 '0 all whom it may concern I Be it known that 1,5 OIIN; J. DARRAGH, acitizen or" the United States, residing; at Memphis, in the county ofShelby and State of Tennessee, have invented certain new and usefulImprovements in Siphonsand Supporting Means for the Same, of which thefollowing is a specification.

The present invention relates tosiphons adapted to beused on waterbottles, as supplied filled to ofi'ices, dwellings, and consumers ingeneral. These siphons are provided with means for supporting themadjustably on bottles of different sizes, or on other containers holdingliquids, Whether such containers are open or closed.

Such water bottles are delivered filled with drinking water and theusual manner of using them is to invert the bottle in a stand afterremoving the stopper, the bottle being gradually emptied by drawingwater from a faucet on the stand or cooler.

As these bottles are comparatively large, holding about five gallons ofwater and with practically smooth sides, they are very difficult tohandle, and can hardly be inverted without spilling some of the water.They sometimes slip from the operators hands, while being handled andare smashed on the floor, causing the loss of both water and.

bottle, not to mention damage to carpets and Sometimes the personhandling these containers is severely cut by their breaking and there isalso danger of injuries by strains caused by the direct lifting of suchheavy containers.

In order to avoid such accidents,-thepresent invention aims at emptyingthebottle or container when in an upright position, after it has beenplaced on a suitable stand or a table, which emptying can be donegradually as the water or other liquid is required during the day. s

In the accompanying drawing one embodiment of the invention isillustrated, and- Figure 1 is a vertical section of a water bottle withthe siphon in position; and

Figure 2 is a perspective View of the attachment for the siphon.

In the drawing,reference numeral 10 represents a bottle of the usualkind for delivering Water to households and oflices, and this bottle isplaced on a suitable stand 11 in the usual manner.

The neck of the bottle is filled with a cork or stopper-12, throughwhich extends a short tube or, vent 13 of glass or metal for admittingaininto the bottle. This tube, Which may be straight or, as seen in thedrawing, L-shaped, extends with its lower end 141a little below theinner end of stopper 12, while its outer or. upper end 15, which may bebent at right angles to the portion in the stopper, terminates outsideof the latter and may bethreaded as at 16 to receive an air pump. WVhenthe siphon is used in open containers no stopper is needed, it beingpossible to use the siphon in open containers by pouring liquid in thesiphon while holding it upside down, then placing the siphon in thecontainer, when the liquid in the siphon will cause the liquid in thecontainer to be drained. l The siphon proper 17 consists of astraightinner leg or pipe section 18te'rn1inating near the bottom of the bottleand held in position by the stopper 12, through which it extends and is'bent as at 19 at right angles continuing downwardly to form an outerleg or pipe section 20, which may follow the contour of the bottle ifthe latter is of standard size and shape, as seen in Figure 1, or ifused for other bottles. or open containers, the siphon'may be, of'U-shape. e V

The lower end of the outer leg 20 is provided with a valve 21, fromwhich extends, below the bottom .ofthe bottle, a nozzle 22. This valve21 is preferably situated below the lower end of the. inner leg 18 inorder to dirainthe bottle completely. By means of this valve a column ofwater is always retained between each individual draining, so thatwhenever-the valve is opened this column is ready to raise and draw morewater out of the bottle or container.

In order to secure the siphon on the bottle, a bandorfhoop 230imetalwire or any other suitablematerial is coiled as at 24;, once or twicearound the outer leg 20, and this hoop ,is made of a size suitable toembrace the bottle 10. It isevident that if flexible material is usedfor this hoop and the ends v made to overlap each other, the hoop may beexpanded to fit difierent size bottles, thus making the deviceadjustable.

The siphon 17 may be made of glass, rubber, metallic tubing or othersuitable material and the inner and outer legs 18 and 20 may be made inone piece or connected by a flexible transverse portion 19 if sodesired. It the two legs are made of separate straight pieces of tubing,they may be connected to a straight cross piece by elbows to facilitatecleaning.

The use of the siphon is not limited to water, but it may be applied tobottles or other containers holding liquid such as oil, vinegar, cideror the like. After the bottle has been placed in an upright position onthe stand 11, its cork is replaced by the stopper 12, carrying thesiphon 17 together with the air tube or vent 13, and the hoop 23 slippedover the bottle so as to hold the outer leg 20 tightly against the same.By the use of a small air compressor, such as a bicycle pump or the likeon the threaded end 19 of the air tube or vent 13, the air above thewater level in the bottle is compressed until the water runs out at thenozzle 22, when the faucet or valve 21 is open. In this manner a columnof water is forced through the inner leg 18 and into the outer leg 20,so that both of them are filled and the faucet or valve 21 is thereuponclosed and the air pump removed from the air tube or vent 18. Directlythis is done, the .air above the water will have atmospheric pressur butwhen the faucet or valve 21 is again opened, the higher column of waterin the outer leg 20 will raise the water from the bottle through theinner leg 18, so that water will run out through the nozzle 22. As theinterior of the bottle connects with the atmosphere, any quantity drawnwill be replaced by air through the tube or vent 13. Preferably a smallcheck valve 26 is inserted in this tube or vent 13 so as to prevent dustand foreign particles from getting into the container. This is a one wayvalve, which may be closed by a light hair spring, so that it willremain shut until the water is being drawn, when the air from theoutside will open this valve against the reduced pressure in the bottlecaused by the withdrawing of the water.

The utility of this device is evident, as distributors of distilledwater and mineral water are aware of the reluctance of oonsumers to usethe large, heavy and cumbersome containers, in which the distilled ormineral waters-are generally delivered, for the reason that it is verydihicult to invert the bottles and place them on the stand orreceptacle. Accordingly people do not buy distilled or mineral waters insuch quantities as would otherwise be the case. By'the use of thesiphon, with the flow of water controlled by a valve, forming thesubject matter of the present invention, the invertin of the bottlesis'entirely avoided and the bottles are drained easily in small or largequantities as may be needed.

It will be evident that the flow of water or other liquid from thebottle or cistern is entirely under the control of the valve 21,because, whenever thisvalve is closed, a column of water will remain inthe siphon, which column is ready to lift and draw water from thecontainer into a glass or receptacle whenever the valve is again opened.

One advantage of the use of this siphon beside that of not having toinvert the bottle when placing it on a stand is, that the siphon is noteasily broken, particularly if made of a non-corrosive material such asblock tin pipe, and does not get out of order. The water coming directlyfrom the bottle instead of having to pass through any intermediaryreceptacle, would be sure not to be contaminated in any way, as no dustfrom the outside of the bottle can pass into the water.

Having thus described the invention what is claimed as new is:

The combination with a liquid receptacle having a reduced neck defininga shouldered portion, a stopper fitted in the neck of the receptacle, arelatively short vent tube extending through the stopper and having oneend thereof communicating with the interior of the receptacle and itsother end provided with means for communication with a source of airsupply, a siphon including an inner leg passing through the stopper andextending to a point near the lower end of the receptacle and an outerleg connected therewith and bent to conform to and resting on theshouldered portion of the receptacle, the lower end of the outer leg ofthe siphon being offset and extended down wardly, a valve secured to thelower end of the outer leg and provided with a discharge nozzle, and asupporting band encircling the receptacle and provided with a loopthrough which the outer leg of the siphon extends near its said ofisetportion for holding said outer leg in contact with the shoulderedportion of the receptacle.

In testimony whereof I affix my signature.
